Here are a few brand-new and newer ASTM specifications (and some discontinued and replaced ones, too).

• ASTM A992/A992M -- The new 50 ksi steel for wide-flange shapes (only) that replaces ASTM A36, ASTM A572 grade 50 and the similar dual-certified products for wide-flange shapes (only). Read about this in three places: Are You Properly Specifying Materials? Part 1 -- Structural Shapes from the January 1999 issue of AISC's Modern Steel Construction magazine, Steel Industry Embraces ASTM A992 from the April 1999 issue of AISC's Modern Steel Construction magazine and AISC Technical Bulletin No. 3, which was AISC's announcement of ASTM A992 before it had an ASTM number. Also, note that 50 ksi W-shapes are now less expensive than 36 ksi W-shapes, as explained here.
• ASTM F1554 -- The new ASTM specification for anchor rods (what used to be called "anchor bolts"). Read about this in Are You Properly Specifying Materials? Part 3 -- Fastening Products from the March 1999 issue of AISC's Modern Steel Construction magazine.
• ASTM F1852 -- The new ASTM specification for twist-off-type tension-control bolt assemblies that meet mechanical and chemical requirements similar to ASTM A325 high-strength bolts. Read about this in Are You Properly Specifying Materials? Part 3 -- Fastening Products from the March 1999 issue of AISC's Modern Steel Construction magazine.

And here are ASTM Specifications that have been discontinued or replaced:

• ASTM A687 was discontinued (1999) without replacement.
• ASTM A570/A570M was discontinued (2000) and replaced by ASTM A1011/A1011M.
• ASTM E142 was discontinued (2000) and replaced by ASTM E94.
